AP Computer Science Principles introduces students to the breadth of computing — from how computers represent data and execute algorithms to the ethical and social impact of computing innovations. The course emphasizes computational thinking, collaboration, and creative development through programming.
Equivalent to a one-semester introductory college course in computing fundamentals.
Single-select multiple choice only — multi-select questions were removed in the 2024 redesign. The AP CSP Reference Sheet (pseudocode, list operations, robot commands) is provided during the exam.
